Cylinder work in the cylinder block (cylinder crankshaft shell) or cylinder jacket of internal combustion engine or other reciprocating piston machines
Make face, bears strong friction stree in operation.Therefore cylinder block is being manufactured or when cylinder jacket importantly, processing in this way
These cylinder bearing faces so that later under all operating conditions, by lubricant film ensure adequately lubrication and
The frictional resistance between component moved relative to each other is kept as small as possible.
This inner face that load can be born in tribology, quality-determining final processing is usually with suitable honing side
Method complete, the honing method typically comprise multiple continuous phases after honing operation.Honing is with not knowing geometrically
Cutter cutting working method.In honing operation, the hone that can be expanded is having in drilling to be processed in order to punching
Journey frequency generates the axial reciprocating motion along drilling and up and down or moves back and forth, and at the same time in order to rotational frequency generate with
It moves back and forth the rotational motion of overlapping and rotates.Be mounted on cutting material body on hone by cutting material body into
The centripetal force acted on one radial to tool axis to system is pressed on inner face to be processed.In honing usually in institute
State the intersection grinding pattern generated for Honing process typically with the cutter trade intersected on inner face, the processing of the intersection
Trace is also referred to as " honing rill ".
In order to there is workpiece preparation to be processed to be used for honing, preposition the smart preprocessing to drill, the pre-add can be passed through
Work is otherwise referred to as finish turning or smart perforating.It is bored with the essence that the smart boring bar tool with cutter determining in size and geometry executes
Hole operation is commonly used in, and determines desired position and the Angle Position of drilling, is also used for generating the cylindrical moulding of stray circle when necessary
Borehole shape.A vital task compared to the honing operation of the smaller machining allowance of essence drilling is that generation is required
Surface texture.
As the requirement of economy and the feature of environmental protection to motor is higher and higher, optimize friction system piston/piston ring/cylinder
Working face is particularly important, to reach the friction, the abrasion of very little and the oil consumption of very little of very little.It is drilling and surface texture
The moulding (macroshape) of macroscopic view is especially important herein.
In some method for fine finishing, produces one kind by means of essence drilling and/or honing and deviate considerably from cylindrical
Borehole shape.Generally axially and/or peripherally direction is asymmetric for these borehole shapes, because the deformation of cylinder block is usually not
It is symmetrical.Under operation, cylindrical as ideal as possible should be generated mostly, thus piston ring beam is entirely boring
Hole Zhou Shangjun can be sealed well.
Different hone types is had developed based on various requirements.They can first be divided into during processing
It can the hone that fed and the hone that can be pre-adjusted.The hone that can be fed during processing can further be drawn
It is divided into: formula hone, such as single formula hone, a plurality of formula hone and specific purpose tool；And it is as comprehensive as possible

In the drilling for having big notch, some problems are likely to result in using a traditional formula hone.Each institute
Although the hone stone of guidance can be responsible for the concentric optimal circularity for expanding and drilling, when notch is very big, there are their hooks
Hang over the risk in workpiece.In addition, so-called shell-type tool is had developed for these service conditions, and in shell-type tool, cutting
Device arrangements are on the wider cutting material body bracket in peripherally direction.Shell-type tool can be for example only with two cutting materials
Ontology bracket (half-shell) is constituted, and also (is corresponded to the cutting material body bracket composition of three or four or more when necessary
Lesser circumferential width).
Shell-type tool can be designed with different structures.
Disclosure DE 1652074 illustrates a kind of hone, has shell-type section, and the cutting of shell-type section is thin
Layer is integrally manufactured as sintering part and the bracket as cutting thin layer has multiple outwardly projecting ribs.
102013204714 A1 of DE for example discloses the hone for being designed to shell-type tool, which is suitable for
The drilling of rotational symmetry is processed, drill the drilling section for having that diameter is different and/or moulding is different.Here, can for example process
And/or generate doleiform, taper or barrel-shaped drilling.Corresponding honing method is otherwise referred to as " profile honing ".Hone tool
There is the cutting group for the annular that can be expanded, cutting group has the cutting material body of multiple circumferential distributions around tool body, cuts
That cuts material body is less than the effective outer of when cutting material body and being fully retracted cutting group by axially measured axial length
Diameter.Cutting group has multiple cutting material body brackets that can radially feed, and the cutting material body bracket is covered each by
Greater than the circumference angular region of the axial length of cutting group.
Shorter axial length based on cutting group, this hone are particularly well applicable for generating axial profile
And/or the already existing axial profile of tracking drilling.In addition, the axial length of the very little of cutting group is advantageous, so as to
Enough surface pressures are generated for processing.By make cutting group have it is multiple it is can radially feeding, be covered each by greater than cutting group
Axial length circumference angular region cutting material body bracket, may also reach up, such as can be in the peripherally direction top gem of a girdle-pendant
Cross drilling of the bridge joint in the wall of cylinder bearing face when mill, thus it is very short in axial direction although cutting material body, but not go out
The risk of non-uniform processing in the range of present cross drilling.It may be accompanied with when using this hone in drilling
Minimum honing overflow work on axial end, the problem of abrasion without adjoint non-uniform cutting body.No
It crosses it should be noted that in drilling (such as doleiform, taper or barrel-shaped drilling) Shi Keneng of processing non-columnar under certain situation
The different surface texture in part is produced based on different cutting depth.These surface textures may cause technological deficiency.Not
Under desired excessively high local roughness depth, it can for example increase oil consumption or gas leakage.If part produces too small material denudation,
It would be possible that being made based on the material damage from preposition processing stage is eliminated very fewly in running armful of cylinder risk of internal combustion engine
It increases.It is likely to occur cutting pattern near the axial end of drilling and cuts the inclined of pattern in drilling rest part
Difference.
Summary of the invention
The task of the present invention is, the method for fine finishing that this hone is provided and can be executed with the hone, it
Allow for, the different drilling of processing modelling in this way so that processed bore surfaces on entire drillable length all have energy
The surface texture well defined.
In order to solve this task, the present invention provides it is a kind of have the right to require 1 feature hone.Additionally mention
A kind of method for fine finishing for having the right to require 13 feature is supplied.Advantageous extension design scheme is said in the dependent claims
It is bright.The content that the wording that all authority requires is explained with reference to book is formed.
The cutting group that can be expanded being mounted on tool body has multiple cutting material body supports that can radially feed
Frame, the cutting material body bracket be covered each by a circumference angular region and by means of be arranged to cutting group a cutting group into
It can radial to tool axis be fed to system.Circumference angular region can for example be in 30 ° or 30 ° or more, 40 ° or 40 ° or more
Either about 60 ° or 60 ° or more or even 90 ° or 90 ° or more.Each cutting material body bracket is held on its radial outside
Multiple narrow cutting material bodies are carried, the cutting material body is mutually arranged with lateral spacing relative to each other and difference
Only cover the sub-fraction of circumference angular region.Therefore there are without the gap or sky for cutting material between cutting material body
Gap.It is possible thereby to ensure reliably to be lubricated and ensured with cooling lubricant filling for process residues under strong material denudation
The discharge divided.
Cutting material body is configured to the narrow cutting material strips in peripherally direction, and the axial direction compared to cutting material strips is long
The width of degree, the cutting material strips peripherally direction is smaller.It can be reached when needed by means of cutting material strips and entirely drilled
In length and on boring end especially uniform covering, can expect honing overflow on end.In axial length
Peripherally direction has the Aspect Ratio between width to be measured to be such as in the range of 4:1 to 20:1.
Cutting material body can be made of completely cutting device or have bracket for example made of metal, the support
Frame carrying cutting device.Cutting device can be for example with cutting made of diamond or made of cubic boron nitride (CBN)
Particle, the particle combine in metal or ceramic matrix.
Cutting group has cutting material body, and cutting material body is not directly or without intermediary to be applied to attached cut
It cuts on the outside of material body bracket and is also not and be rigidly or securely attached thereto.It more precisely defines, In
Arranging in gap between cutting material body and the cutting material body bracket of carrying cutting material body can elastic buckling
Middle layer, the middle layer be filled in cutting material body and cut material body bracket between gap.
This middle layer can be set in all cutting material bodies of a cutting group.It is also possible that only cutting
A part cutting material body for cutting group carried by this middle layer and another part rigidly with carry its cutting material
Ontology connection.Cut all cutting material bodies of material body bracket preferably otherwise by elastic middle layer yieldly with
Be arranged cutting material body bracket connection or whole rigidity be fixed on this cutting material body bracket on, thus
There is no the mixing with the cutting material body yieldly coupled of rigidity on cutting material body bracket.
Each cutting material body bracket therefore there are two carrying belts, three, four, five, six, seven, eight or
The cutting material body group for more distinguishing relatively narrow cutting material body, the peripherally direction between the cutting material body
There are gaps.It cuts material body group (group of cutting material body) and passes through substantially rigid cutting material body bracket itself
Carrying, thus when cutting material body bracket is radially fed, cut all cutting material bodies of material body group
Jointly radially it is fed.Requirement to the radial feeding of cutting material body bracket causes, bracket relative to
Workpiece body must be supported in a manner of movable, wherein firstly the need of movement radially.But it may be for example in honing
Certain inclination of cutting material body bracket can not be excluded in the region of overflow completely, because there if the end on observation
Generate the different loads of cutting material body and therefore attached cutting material body bracket.
Pass through the elastic buckling between cutting material body and the cutting material body bracket of carrying cutting material body
Middle layer, obtain (rigid) cutting material of the opposite carrying cutting material body of cutting material body in a certain range
The respective flexibility of other cutting material bodies of ontology bracket and opposite cutting material body group can motility.
Shown thus can also further to improve compared to traditional solution hone or cutting material body with have it is to be processed
Surface different orientations matching.
The evolutionary approach can be especially in the axial mistake in taper and/or between cylindricality and the drilling section of taper
It crosses in the axial transitional region in region and/or between the section of different bevel angles and obtains.In addition, cutting material body must
When wanting also having deposited for drilling can be preferably tracked in the case where the borehole shape or roundness deviation of the ellipse of higher levels
Roundness deviation.The improvement side in the region of the rollback point of the honing movements carried out back and forth along axial direction is also obtained when necessary
Case in the place, can be generated to be applied to and be cut by cutting material body and carrying that is, in such a place when direction switches
Cut the heeling moment on the device of the cutting material body bracket composition of material body.
It may also reach up by middle layer, cut material body although (having since whole device may be applied to
Cut material body cutting material body bracket) on heeling moment, still keep being parallel to processed bore surfaces as far as possible
Thus ground orientation until can also guarantee in the different axial transitional region of surface orientation and on the boring end of axial direction
The uniform surface texture that can well limit.By making middle layer be filled in cutting material body and cutting material body bracket
Between gap, not will cause in cutting material body and cut the abrasion between material body bracket, thus even if entire
Respective flexibility is also able to maintain in the case of strong material denudation during honing process.Therefore it can equally prevent because of scratch
And/or surface damage caused by rill, the surface damage may be by abrasion dirt and/or rough cut grain or foreign matter in elasticity
Deposition in the portion of leaving a blank of strip-like carrier occurs.
Hone according to the invention is particularly suitable for the drilling that honing has axial profile.Respectively by flexiblely or in the wrong
The gradient for taking the Axial changes that the cutting material body that ground supports can particularly good drill with the edge of drilling inner face matches,
Such as in the transition region between the drilling section of cylindrical drilling section and taper.Cutting material body should be as good as possible
The honing operation for tracking macroscopical moulding of the profile of drilling without changing drilling well is also referred to as " tracking honing " herein.In
To in the Honing process with rotational symmetry non-circular borehole shape devious, can use by hone of the invention
Advantage.
Known by a large number of experiments, it typically is advantageous to, middle layer have within the scope of 0.1mm to 2mm, particularly
Thickness within the scope of 0.5mm to 1.5mm.In the thickness significantly lower than lower limit, cutting material body is opposite to cut material body
The energy obliquity that can thus reach of bracket component is not sufficient to that balance can be createed in the fault orientation occurred.In
It is apparently higher than in the thickness of the upper limit, obtains cutting material strips and become increasingly difficult relative to the enough stability of lateral load.
In order to allow in middle layer relative to the enough stability of lateral load and for the enough of balance errors orientation
Flexibility between reach good compromise, be proved advantageously, the Shore hardness of middle layer is in about 70 Durometer A hardness extremely
In the range of 95 Durometer A hardness.Under greater hardness, enough surrenders are usually no longer provided.In significantly smaller hardness
Under, arrangement of the cutting material strips on cutting material body bracket component can become excessively unstable, thus in Honing process
Shi Buzai can take enough operating forces on surface to be processed.
In a preferred embodiment, middle layer has the elastic polyurethane system by elastomer, particularly caoutchouc elasticity
At elasticity layer.Term " elastomer " represents dimensionally stable but energy flexible deformation plastics, its glass transition herein
Point is in using under temperature.Elastomer can be resiliently deformed under tensile load and pressure load, but be returned to it later
Initial undeformed moulding.This elastomer can be manufactured for example by the vulcanization of natural rubber or silicon rubber.It can be especially good
The elastomer that can be bonded is utilized well.One advantage of polyurethane elastomer is the influence relative to typical cooling lubricant
, the particularly preferred stability of material property.
It provides in some embodiments, middle layer directly vulcanizes on the contact surface at cutting material body or cutting material
On the outside for expecting ontology bracket component.In this case, in order to set up in middle layer between element adjacent therewith
Connection, does not need other material (such as increasing attached dose or bonding agent).With other elements (cutting material body or cutting material sheet
The outside of body bracket component) the connection of plane can for example pass through thin adhesive layer and realize.
In some embodiments, middle layer has multi-slice or multilayer structure.Middle layer can especially be built in this way,
So that the second layer that there is first layer and at least one plane earth to connect with first layer for it, wherein first layer is by elastic system
At layer and the second layer be the adhesive layer being connect with first layer plane earth.
It is preferred to provide although adhesive layer (second layer) may be thicker than elastomer layer (first layer), the layer of first layer
Thickness is greater than the thickness of the second layer.It is possible thereby to which what is reached is, it is determined that the characteristic of first layer (elastomer layer) is to cutting material sheet
The desired surrender of the opposite cutting material body bracket component of body or flexibility have important contribution.
It is possible that the contribution that adhesive layer makes the integral, flexible of middle layer may be smaller.Thus this point may be
Reach, that is, adhesive layer itself can be resiliently deformed.In order to manufacture adhesive layer, such as using viscoplastic bonding agent, such as
The viscoplastic two-component plastic bonding agent of acrylic acid alkali.When selection is used for the material of adhesive layer, should preferably pay attention to
, exist and deposited compared to the material of cutting material body and/or the material in the opposite outside for cutting material body bracket component
In good adhesive strength.
It, can be by least one face in the face adjacent with adhesive layer in order to improve the adhesive strength on bonding site
Pass through sandblasting or grinding before applying bonding agent or becomes coarse in other ways.Such as the cutting material body being formed from steel
The average roughness depth R in bracket and/or cutting material body the face adjacent with adhesive layerZIt is in RZ =10 μm to RZ
In the range of=30 μm.Thus, it is possible to reach persistently high adhesive strength.Intermediate layer material (such as made of polyurethane elastomer
Plate or band) the face contacted with bonding agent also can become in advance coarse.Here, in RZ =15 μm to RZ =40 μm
Average roughness depth in range is proved particularly advantageous.
The present invention can be used in different hone types.Cutting material body bracket for example can be along axial ratio
Peripherally direction is longer.In many embodiments, cutting group then has along axially measured axial length, and the axial length is small
In the effective outer diameter of the cutting group when cutting material body and being fully retracted.This cutting group is properly termed as the cutting group of annular.
In the cutting group of annular, cutting material body also can be configured to the narrow cutting material strips in peripherally direction, compared to cutting
The axial length of material strips is cut, the width in the cutting material strips peripherally direction is smaller.
Hone preferably has the cutting group of just what a unique annular.Annular cutting group may be designed so that,
So that in the axial section covered by the cutting group of annular, it may be than in traditional hone with relatively narrow hone stone
In relatively narrow axial section, there are contact surfaces much more, between cutting material body and the inner face that drills.
The axial length of cutting material body can be, for example, less than the 40% of the effective outer diameter of hone or less than 30%,
Especially between the 15% to 30% of this outer diameter.It drills in the typical cylinder of the motor cylinder for processing car or lorry
Hone in, axial length is for example between 5mm to 40mm, particularly 10mm to 35mm.Reference needs
The drillable length of the drilling of processing, axial length can for example be less than the 20% of this drillable length or less than 10%.Reference needs
The bore diameter of the drilling of processing, the axial length can be for example in the range of the 20% to 50% of bore diameter.
Because cutting material body compared to traditional hone stone along axially shorter, institute in the cutting group of this annular
With even if having relatively small thickness (such as produced in the stable middle layer of 0.5mm to 1.5mm) cutting material body and
Sufficiently strong inclination angle between tool axis, is thus conducive to the special ability of Contour tracing.
When being equipped at least three cutting material body brackets in cutting group, then operating force is in the entire of hone
It can be evenly distributed in well and more on the periphery of cutting group by energy on the available effective outer diameter of expansion.Can for example it exist
Just three, just four, just five, just six, just seven or just eight identical Zhou Biankuan are set in cutting group
The cutting material body bracket of degree or different circumferential widths.The cutting material body bracket for being more than eight in a cutting group
Although feasible, structure design can be made to become increasingly complex and usually necessary.In some cases, honing work
Only tool, may be also enough if necessary there are two material body bracket is cut for tool.
There are some embodiments, in these embodiments, all cutting material body brackets of hone or all
Cutting material body can be with unique primary common feeding by along radial feed.This hone is known as with single expansion
The hone opened.Other embodiments are characterized in that hone is designed to the dual hone expanded.In
In this hone, cutting group includes first group of cutting material body bracket and second group of cutting material body disconnecting
Bracket, wherein first group and second group can feed independently of each other.Using this adjoint dual hone expanded
When, be able to achieve method for fine finishing, in method for fine finishing, one group of cutting material body bracket respectively by jointly along radial direction into
It gives and bounces back.It is possible thereby to for example will wherein one group by bounce back and drilling inner face disengage rabbet, thus drill inner face only use
Another group is processed.It is also possible that drilling inner face is processed with the cutting material body of first group and second group simultaneously.
Shorten the potentially possible of cycle time using providing with the dual hone expanded, because also can when necessary
Cancel continuous phase after different honing operations between tool changing.In some embodiments, it is first held with first group
The first preposition honing operation of row, this first group bounces back later, another group (second group) is then preferably simultaneously with first group
Retraction is radially outward fed and is executed later with second group of cutting material body the second honing operation of postposition.
First group and second group of cutting material body can have in total different degrades characteristic or other for material
Degrade identified characteristic.Two groups of cutting material bodies can have different width and/or for example with different periphery spacing
And/or different indexing is installed on the cutting material body bracket being separately equipped with.It is alternative or additional it is also possible that wherein one
Group cutting material body equipped with thicker particle be used for rougher processing, and another group of cutting material body equipped with compared with
Thin particle is used for finer processing.Therefore for instance it can be possible that being implemented before and after successive with identical hone adjoint
The final honing of the pre- honing operation of substantial material denudation and adjoint lesser or almost without material denudation postposition is grasped
Make with the surface of smooth structuring before.
Outstanding place with some embodiments of the dual hone expanded is, in the first set, cuts material
Material ontology has been directly anchored to the cutting material body bracket being arranged in the case where the middle layer of no intermediate connection elasticity
Above and thus it is rigidly connect with cutting material body bracket, and in the second set, cut material body respectively elastic buckling
Ground is fixed on cutting material body bracket be arranged by the middle layer of elastic buckling.It for example can first be used with dual expand
First group, to execute the first honing operation for being designed to profile honing operation, thus targetedly based on processing before
Change the axial profile of drilling.Later first group with drilling inner face disengage and second group with drilling inner face interlocking, so as to
Second group of execution form be track honing operation the second honing operation, in the second honing operation, only mild wear and
The cutting material body kept to elastic buckling substantially tracks the profile generated before and improves surface texture first.
The present invention also relates to a kind of method for fine finishing, for processing the inner face of drilling in workpiece, particularly for making
Cylinder bearing face is finished when making the cylinder block or cylinder jacket for reciprocating piston machine.In the process of the method for fine finishing,
At least one honing operation is executed, in the honing operation, the hone that can be expanded is generated in drilling along drilling
Axial reciprocating motion and move up and down and at the same time being rotated to generate the rotational motion Chong Die with the reciprocating motion.At this
The hone according to claimed invention is used in a honing operation.This honing operation is preferably multistage essence
The last finishing operations of processing method and the surface texture of finished product is mainly determined.
Before starting honing operation, can by essence drilling (cutter determined with geometry), by honing (with several
What uncertain cutter of shape) or by the combinations (such as first essence drilling, honing later) of two kinds of method for fine finishing produce with
The borehole shape of cylindrical substantially deviation.Drilling can be for example pre-machined in this way, so that drilling starts it in honing operation
Preceding axial profile of living moves towards (such as barrel-shaped, doleiform or taper) and/or with targetedly non-circular shape (example
As ellipse or cloverleaf pattern) one or more sections.The honing operation is then with being kept substantially shape in this way
It executes, so that being generated on drilling inner face using hone in the macroshape for not substantially changing drilling
Final desired surface texture.Here, pre-determined molding surface is followed or tracked to cutting material body, wherein by each
The bearing of a cutting material body respectively surrendered obtains particularly good trace ability.

As can be seen in Figure 1 like that, each cutting material body bracket has more on its radial outside 154
A form is to cut the cutting material body of material strips, and the cutting material strips are with the cloth relative to each other of periphery spacing to each other
It sets.The cutting material of these cutting material body groups or the cutting material strips being commonly mounted on a cutting material body bracket
Item group can be for example made of the cutting material strips between three and ten.In sample situation, in each cutting material sheet
Seven cutting material strips are arranged with uniform periphery spacing to each other on body bracket.Periphery spacing is in more narrow cutting material
In material strip for instance in cutting material strips width the order of magnitude in or be greater than the order of magnitude, in wider cutting material strips then
Such as it is in the size for cutting the width of material strips or is less than the size.
Cutting material body is not rigidly to connect with the cutting material body bracket for carrying them.Instead
Wherein there are a gaps between each cutting material strips and the cutting material body bracket for carrying the cutting material strips, at this
Arrange that the middle layer 160 of elastic buckling, the middle layer are substantially completely filled in cutting material strips and cutting material in gap
Gap between ontology bracket component.Reached by the middle layer of elastic buckling, cutting material body is under external load
It can limitedly be moved with respect to cutting material body bracket with limited range and with overcoming the reset force as caused by middle layer.It cuts
It cuts material strips and is respectively provided with respective flexibility herein, therefore independently can slightly be moved with adjacent cutting material strips respectively
It is dynamic.
Middle layer has the thickness SD of about 1mm in an exemplary situation, and thus, it is possible to reach in enough surrender property and cutting material
Expect ontology relative to the good compromise between the sufficient stability of cross force.Middle layer is substantially by hardness in 75 and 85 Xiao
The polyurethane elastomer of the caoutchouc elasticity in hardness range between family name's hardness A is made.The polyurethane plastics example of applicable elasticity
As being bought in the market with trade (brand) name Vulkollan or Urepan.Intermediate layer material is non-porous, is sealing,
Because without having, cooling lubricant is invaded and the characteristic of elasticity enduringly keeps stable.The material is also cold-resistant in chemistry
But lubricant and the abrasion of Honing process is also mechanically sufficient to resist in severe processing environment.
It is possible that thin, the narrow band of the pre- batch production of intermediate layer material is first adhered to when manufacturing hone
It cuts on material body bracket and later by the cutting material body of bar shaped set thus (cutting material strips) with suitably
Bonding agent bonding.
In a kind of variant schemes of the manufacture, without increasing attached dose between intermediate layer material and cutting material body.
In this variant schemes, one block of plate first is manufactured with cutting material body material.It later will be by before the intermediate layer material that makes
The vulcanization of layer made of object is driven to being set as on the side of fixing layer (contact side), thus is produced by vulcanization and is cutting material sheet
A kind of mechanically firm attachment contact between body material and intermediate layer material.And then it can be cut by separating coating
Material body plate is cut to manufacture each cutting material body for being respectively arranged with middle layer.It is also possible that each cutting material
Side is provided with the elastomer layer of vulcanization respectively for item and then this elastomer layer is bonded to cutting material body bracket
On element.
It is also possible that first with a layer made of intermediate materials more or less comprehensively (such as passing through bonding) to cutting
Cut material body bracket component outside carry out coating, and later by bonding by cut material strips be fixed on thus set by
On position.Then intermediate layer material is kept freely (referring to Fig. 5) between adjacent cutting material strips.
In order to set up the bonding of the plane between cutting material body and the band made of the intermediate layer material of elasticity
Connection and/or the bonding between the middle layer made of polyurethane plastics and the outside of cutting material body bracket component connect
It connects, uses the viscoplastic bicomponent structure bonding agent of acrylic acid alkali in a preferred embodiment.Thus obtained bonding
It is outstanding place be high-adhesion.In addition, adhesive layer itself is slightly elastic, thus generate a kind of multi-slice
The middle layer of elastic buckling, the middle layer provide good attachment after lasting alternate stress.
When intermediate layer material, cutting material body bracket and/or the face contacted with bonding agent for cutting material body have
When more coarse surface texture, it may be implemented to improve adhesive strength.Surface can lead to before applying bonding agent if necessary
It crosses grinding, sandblasting or becomes coarse in other ways, such as reach in RZ =15 μm to RZ It is average thick in=30 μ ms
Rough depth.
By the middle layer of connection elastic buckling intermediate between cutting material strips and cutting material body bracket component, lead to
The ability that Contour tracing of the hone when processing and/or having the drilling of axial profile trend can often be improved, because
It is slightly aligned for cutting material strips compared to the cutting material body bracket component of rigidity and therefore can reach drilling inner face
On more uniform pressing.
